Speaking out: Tori Spelling, pictured in Los Angeles this weekend, discusses her heartbreak in a new interview with Us Weekly

She was left heartbroken and devastated following the revelation that husband Deam McDermott cheated on her with a 28-year-old woman named Emily Goodhand over a weekend in Canada last December.

And now, Tori Spelling has spoken out in a new interview, revealing she and her 47-year-old husband have not had sex since December while voicing fears her marriage may not survive.

'If I can't ever let my guard down again, then there can't always be a relationship,' she told Us Weekly. 'I always said "If he ever cheated on me I would be out of there! Whether I can ever trust him again. That's the big question.'

Admitting the couple had not had sex since December, Tori said the Canadian actor had not yet moved back into their Encino home and said he stayed over at the house at her discretion.

'There are children involved,' she said referring to Liam, seven, Stella, five, two-year-old Hattie and 20-month-old Finn. 'I need to try to figure this out. You don't stop loving someone because they do something really bad to you.

'It makes you not trust anything that's happened in your relationship. But until I figure that out, I don't want the kids to know any different.'

The fall out from Dean's infidelity will be detailed in depth in the couple's new reality show True Tori. He is seen on camera admitting the two day fling with Goodhand.

'That's my worst nightmare [that] I cheated on my wife,' he says. 'I was out of control,' Sex was an escape, just like drugs or alcohol.'

Tori tells Us she was first alerted to the cheating report after a call from her publicist, but dismissed it as another 'crazy' story.

Dean initially denied it, but when the piece was published in a magazine a week later, began to change his story.

'He was very nervous - I saw it in his face,' Tori recalled. 'He said that they had kissed but that was it. I knew in that moment the worst had happened. I said "I don't believe you for one second. I don't believe that's all."'

Tori describes how the couple lay down side by side and Dean 'talked me through the entire weekend with Emily.'

She said: 'He didn't want to get graphic. I didn't want him to. We kept it to the facts. It wasn't about feelings. I listened and made sure I didn't show emotion. I didn't cry. He didn't cry. He sounded remorseful. He sounded like a husband who had gotten caught.'

Dean took 'full responsibility' for his indiscretions and immediately went into rehab treatment for 30 days back in January.
